Boost your caster level a bit and substitute Solars. Alternatively, summon four efreetis at a time, for free, 13times/day, for three wishes each time. 36+12xCHA mod wishes per day for free is... a little broken. That's one ability, and they can go back to using their customized and optimized eidolon ("hey, lets make a custom item of permanent greater evolution surge!") when that's burned through. Sitting at home in their custom demiplane (they get spells for that)... yeah.
